"The Internet's not going to rewire itself for you; you're going to continue to have machines in between you and the machines that want your password. How do you keep them from hearing that password? You encrypt it!"

"If you don't already have the ssh software on your system (try running the command "ssh" to see), you'll need to download it. First, see if your distribution has ssh or openssh packages included (distributions created outside the US might, distributions created inside the US aren't likely to). One trick is to see whether there might be a server maintained outside the US that has software ready for your distribution; ftp.redhat.de is an excellent place to look for RedHat."

"As this is the first time you've connected, the remote system offers it's host key to you; you should accept it. ... When you connect next time, your ssh client will compare the host key it has with the key coming back from the server to make sure that it's the same system. It'll complain loudly if the key changes... What have you gained? The big gain so far is that every character you type and every screen update that comes back from the server is encrypted; nobody can use a sniffer to see what your keystrokes or screen displays anymore."
